    So, in the process of re-gearing my truck to 4.56, and i seemed to have lost my thrust washer on the passenger side axle flange. I have the locating washer, just not the thrust washer.

    Thrust washer is the top washer.

    My question is, i cannot find the thrust washer on any schematics online. Why is this? Did some come with one and some not?

    Thrust Washer

    Did you ever figure the thrust washer dilemma out? It's been a couple of years, I tore into my 2002 Sierra and I do not have the thicker thrust washer & the lower with the two flanges was damaged inside my passenger side axle. I went to GM dealer today they told me that the flanged washer had a lot of problems so they have revised it to only 1 piece. Once I get the part from the dealer I will take a picture of it for future reference for everyone.

    I did actually get a new thrust washer from wrecker and put it in. Hasn't given me any problems.
